please answer #9 and show original work thank you

This is very similar to the first assignment (with the key difference coming in question nine). An auto parts company is in the construction phase of a new plant in Lake Charles, LA. The centerpiece of the operation is a stamping machine that (in its basic configuration) can process 40 parts per hour (on average). Parts arrive at an average rate of 36 units per hour. Assume all processing (service) times and interarrival times are exponentially distributed. in front of the old the enting tren bemble to 8 9. Suppose the manager now has the option of purchasing a second machine (instead of trying to make the one machine faster as in the above problem). Under the current conditions (1 = 36 and = 40), will adding the second machine in the form of an M/M/2 queue) achieve the manager's goal of no more than two parts in the waiting area? =
